MY 97 ST1100 HAS A WEIRD FLUTTER WHEN IDLING AS IF THE CHOKE IS ALL THE WAY ON. WHEN I PUT THE CHOKE ON I CAN TELL ITS WORKING. FLUTTER DOES NOT GO AWAY WHEN RIDING UNLESS YOU GET INTO THE THROTTLE HARD. DO I NEED A CARB SYNC???

WYATT - Flutter? I don't quite understand. Does that mean the idle goes up and down? Could be a vacuum leak, but a sync would not hurt.

Better check your air filter to make sure it is clean. If you have a K & N or something, you may have over-oiled it.

I'm guessing either vacuum leak or exhaust pipe loose, which one probably depends on the severity of the flutter....
It never, ever hurts to synch carbs.

As others mentioned a sync wouldn't hurt. However if you have a vacuum leak I would look for that first it may make it hard to do a carb sync with a vacuum leak.
THANKS, FOR THE IMPUT!! I WILL START CHECKING FOR VACCUM LEAKS.THE FLUTTER ON MY 97 ST, IS THE SAME SOUND YOU GET WITH CHOKE ON FULL. REVING THE ENGINE DOES NOT CHANGE SOUND. WHEN YOU GET INTO THE THROTTLE, IT GOES AWAY BUT COMES BACK WHEN RIDING A NORMAL SPEED WITHOUT ACCELERATION. FUEL MPG, SEEMS TO BE HIGH 30'S. THE BIKE HAS 8,OOO MILES ON IT.
Why you shouting.
